The surprising Seahawks won on the strength of Matt Hasselbeck’s four touchdown passes, a spongy defense that stiffened at all the right moments and the consistent cacophony of 66,336 spectators at Qwest Field.

One of those highlights was, quite simply, among the greatest runs the game of football has ever seen: Late in the fourth quarter, with the Saints seeming to have all the momentum, Seahawks running back Marshawn Lynch scored on a 67-yard run that will be remembered as one of the best plays in NFL history, an absolutely preposterous display of speed and power on which most of the Saints defenders got a hand on Lynch but no one could bring him down.http://profootballtalk.nbcsports.com/2011/01/08/seahawks-stun-saints-in-a-classic/

Seahawks fans literally shook the Earth in their elation over Saturday's upset of the New Orleans Saints.
During the game's pivotal play — Marshawn Lynch's 67-yard touchdown run — the crowd of 66,336 cheered and jumped and stomped so vigorously that the vibrations registered like a small earthquake on a nearby seismometer.
